Atrial fibrillation An irregular pulse could be a sign that you have an abnormal heart rhythm. Atrial Fibrillation (AF) is one of the most common forms of abnormal heart rhythm and a major cause of stroke. Normally, your heart’s natural pacemaker sends out regular electrical impulses. AF happens when those impulses fire off from different places in the atria (the top chambers of the heart) in a disorganised way.

What causes chronic atrial fibrillation? A Greenville Health System answered. Chronic atrial fibrillation may be the result of heart disease, hypertension, lung disease (emphysema), congestive heart failure, coronary artery disease, hyperthyroidism (overactive thyroid gland) pericarditis, or mitral regurgitation.

- By Mayo Clinic Staff. Stress can contribute to causing heart rhythm disorders (arrhythmias) such as atrial fibrillation. Some studies suggest that stress and mental health issues may cause your atrial fibrillation symptoms to worsen. High levels of stress may also be linked to other health problems.

What acute conditions cause atrial fibrillation (AFib)? There are a number of temporary (acute) that can cause atrial fibrillation (AFib). For the most part, when the temporary condition ceases or is treated, AFib usually is resolved. Many of the acute conditions listed can cause chemical imbalances that may lead to electrical imbalances in your heart, triggering AFib.

Heart Attack (Myocardial Infarction) Permanent brain damage and death can occur unless the flow of blood to the brain is restored within five minutes. Heart attack is the most common cause of ventricular fibrillation. Less common causes of cardiac arrest include respiratory arrest (loss of breathing function), choking, trauma, electrocution, and drowning. Medically Reviewed by a Doctor on 9/8/2014.

Glossary It may come and go. Atrial fibrillation may cause a person to have symptoms, such as episodes of shortness of breath, dizziness or light-headedness. Some feel a thumping in the chest, called palpitations. There are other causes for irregular heart rate besides AF so see your doctor or healthcare practitioner if you have symptoms.

What are the Causes of Atrial Fibrillation? 1 Obstructive sleep apnea commonly causes high blood pressure (hypertension), which in turn raises the risk of heart problems and stroke. 2  Alcohol abuse-regular, excessive, long-term consumption of alcohol is closely linked to a higher risk of developing atrial fibrillation.t is extremely rare for atrial fibrillation to develop in younger patients, unless they have an underlying heart condition. Experts say there are many cases in which the cause of the atrial fibrillation was never found. Here is a list of the most common causes: 1  Hypertension-high blood pressure.

Sudden Cardiac Arrest (Sudden Cardiac Death) The heart muscle can't supply blood to the body, particularly the brain, and the body dies. Ventricular fibrillation (V Fib) is the most common reason for sudden death in patients. Without a coordinated electrical signal, the bottom chambers of the heart (ventricles) stop beating and instead, jiggle like Jello.

Heart Disease and Abnormal Heart Rhythm (Arrhythmia) The most common symptom of atrial fibrillation is palpitations, an uncomfortable awareness of the rapid and irregular heartbeat. Other symptoms of atrial fibrillation are caused by the diminished delivery of blood to the body. angina (chest pain due to reduced blood flow to the heart muscles).

Heart Disease and Abnormal Heart Rhythm (Arrhythmia) 1 Atrial fibrillation is a very common irregular heart rhythm that causes the atria, the upper chambers of the heart, to contract abnormally.  Atrial flutter. This is an arrhythmia caused by one or more rapid circuits in the atrium. Atrial flutter is usually more organized and regular than atrial fibrillation. This arrhythmia occurs most often in people with heart disease and in the first week after heart surgery.

Arrhythmia Arrhythmias can also be caused by certain substances or medications, such as caffeine, nicotine, alcohol, cocaine, inhaled aerosols, diet pills, and cough and cold remedies. Emotional states such as shock, fright or stress can also cause irregular heart rhythms.

Heart disease guide Atrial flutter causes. Atrial flutter may be caused by abnormalities or diseases of the heart itself, by a disease elsewhere in the body that affects the heart, or by consuming substances that change the way electrical impulses are transmitted through the heart.

Overview Ventricular fibrillation. Ventricular fibrillation occurs when rapid, chaotic electrical impulses cause the ventricles to quiver ineffectively instead of pumping necessary blood to the body. This serious problem is fatal if the heart isn't restored to a normal rhythm within minutes.

Atrial Fibrillation When the upper chambers of the heart beat too fast or uncontrollably, blood may pool in the left atrial appendage and form clots, increasing the risk for stroke. About 15 percent of strokes occur in people with a-fib. In addition, if you have a-fib, you may not feel well because your heart is unable to pump effectively.

A Look at Paroxysmal Atrial Fibrillation Causes of AFib. AFib is caused by damage to the heart from heart disease or high blood pressure. Medications and other factors can also lead to AFib. These factors include: binge drinking, or consuming 4 to 5 drinks within 2 hours. stimulant medications and drugs, such as methylphenidate, pseudoephedrine, or cocaine.

Arrhythmia A problem in any of these can cause an arrhythmia. Minor arrhythmias may be caused by excessive alcohol use, smoking, caffeine, stress or exercise. The most common cause of arrhythmias is heart disease, particularly coronary artery disease, abnormal heart valve function and heart failure.

- Cardiac conditions commonly associated with the development of atrial fibrillation include rheumatic mitral valve disease, coronary artery disease, congestive heart failure, and hypertension. The ECG is the mainstay for diagnosis of atrial fibrillation (Figure 1).

Heart Disease and Sudden Cardiac Death Most sudden cardiac deaths are caused by abnormal heart rhythms called arrhythmias. The most common life-threatening arrhythmia is ventricular fibrillation, which is an erratic, disorganized firing of impulses from the ventricles (the heart’s lower chambers). When this occurs, the heart is unable to pump blood and death will occur within minutes, if left untreated.
